Quarry Waste As Fine Aggregate Ppt

Aggregate is mined from the earth either dug out of pits or blasted out of quarries this process has many significant environmental impacts creating the pits or quarries requires the removal of virtually all natural vegetation top soil and subsoil to reach the aggregate underneath not only does this lead to a loss of existing animal.
